Figure 3 is a vertical section therethrough.

Figure 4 is a sectional plane of the rimlush.

Figure 5 is a section on line 5--5 of Fig- In/l the construction of thenpatent above referred to the flushing tank is integral with the bowl andlocated so as to be within the space limits of standard roughing-in d1-`mensions. The flushing is eii'ected by introducing water from the tankinto the bowl below the water seal and in suiiicient volume to raisethelevel within the bowl so as'to establish siphonic action. This is theequivalent of raising the head so that a high velocity is imparted tothe water entering the bowl and passing through the trap to accomplish athorough flushing. The patent referred to also shows a tangential`arrangement of the passage for the water into the bowl to impart arotary movement to the mass of water therein. This is for the purpose ofestablishing centrifugal and centripetal action within the bowl but wehave discovered that such action must be accurately controlled in orderto produce benelicial results. Thus, if the rotary motion is.

too high in velocity, it will throw the water up the sides ofthe bowland produce a vortex that defeats the object of establishing siphonicaction. On the other hand, if no rotary movement is imparted to themass, the flushing action is not as eilicient.

It is one of the features of the present improvement that the waterentering the bowl is so directed and controlled as to -produce just therequisite velocity o f rotation. This is such that centrifugal action ofthe water will produce a centripetal force for plan view in theA`carrying the mass to the centre of the bowl so that 1t is first drawn,through the trap.

of the rixn, this water being directed downy ward against the walls ofthe bowl to roduce an equal washing eil'ect on all portions thereof.Other features of our improvement willbe referred to specificallyhereinafter.

In detail A is a bowl which is supported on a pedestal B having arrangedtherein the' trap comprising the upwaidly and rearwardly extending legC., the downwardly extending leg D and a laterall extending portion Ewhich connects with t e soil pipe. The tank F extends trap B and alsolaterally to a greater width than the bowl, its walls taperin forwardly`to merge into the walls of the owl. Surrounding the top of the bowl is arim G which is hollow and provided with an inwardly extending portion Gon its underside and a series of jet apertures H which are inclined tobe directed 4against the walls of the bowl. At the rear of this rim isan inlet passage I extending into the tank and adaptedI for connectionwith the water supply fitting. Within the hollow rim and extendingaround the rear portion thereof is a series of baille plates J separatedfrom each other suiiicientlyfor the passage of a small amount of watertherebetween butv directing a large portion of the stream to theopposite sides of the rim so as to insure substantially equaldistribution to all of the jets H. The bottom of the tank F ispreferably located but slightly below the level of the water seal in thebowl and has provided therein at one point? an aperture K which connectswith the passage L extending at one side of the pedestal andcommunicating with a port M in the side of the bowl. As shown in Figure5 the passage L in the portionA communicating with the port M is sofashioned that the stream of water entering the bowl is directed towardthe central portion of the mass but slightly to one sideof thegeometrical centre. This will produce a whirling of the water whichhowever is limited in velocity so as to avoid interference with theestablishment of siphonic action.- Nevertheless the rotary movementis'suiilrearwardly from the cient to produce a centrifugal andcentripetal action above referred to which great y assists the flushingaction. The passage L is also connected with an upwardly extendingpassage N within the tank F, this rising to a point sli htly above thenormal level Within the tarili but lower than the top of the rim of thebowl. Thus, should water rise to an abnormal height due to a leaky inletvalve or any other cause, it could overflow through the assage N andescape by way of the bowl and) trap.

The port K which connects the tank with the assage L is controlled by avalve O whic engages a seat member P. This seat member is preferablyprovided with a down turned flan e P extending into the aperture K, an agasket Q, between the seat `imemberA and the bottom of the tank formsthe seal. The seat member is secured in position by bolts R which passthrou h apertures in the bottom of the tank an engage nuts that arelocated in the passage L. Gaskets S normally prevent any leakage aroundthese bolts but should leakage at any time occur, it would be into thepassage L which has free connection with the drain. The seat member P isprovided with an upwardl extending post T at one side thereof whic isturned inward at its upper end and is provided with guide bearin s U forengaging the stem. O of the valve V is an operating lever fulcrumed at Vupon the bracket W at one side of the tank and havin at its free end aloop V2 for loosely engaging the stem O below the loop or head Oz at theupper end of said stem. The lever V may be loperated by a handle X whichhas a crank arm X connected by the link Y to said lever.

Water is supplied to the tank and to the rim through suitableconnections which form the subject matter of another application forpatent and therefore will not be described in detail. Generally theseconsist of an inlet conduit Z passing upward through the bottomof thetank and having at its upper end a fitting Z containing the ball cock.This fitting 1s connected with the downwardly extending dischargeconduit or hush tube Z2 and the laterally extendin conduit Zs leading tothe passage I in t e rim. There is also a vent passage Z* so locatedthat it will normall discharge water when the ball cock is open but willact as an air vent in case of suction in the supply conduit Z.

In operation, the ball cock automatically admits water to the tank up toa predetermined level and also when open supplies a limited quantity ofwater to the hollow rim. The flushing is effected by operation of thehandle X connected to the crank arm X and link Y, which lifts the stem 0and valve O connected therewith permitting the water to flow through thepassage L and port N into the bowl and this raises the level within thebowl to a point where sihonic action is established whereupon the ullvolume of water in the bowl and tank is ra idly discharged at highvelocity. This, coup ed with the centrifugal and centripetal actionabove referred to will effect a thorough cleansing of the bowl. At'thesame time, the lowering of the level within the tank by opening the ballcock supplies water to the hollow rim and the baffles J therein producean cqual distribution around all sides of said rim. This in turnproduces jets of equal force continuing in actionduring the emptying ofthe tank and the refilling of the same and furnishing water after thebreaking of the Siphon for reestablishing the water seal.

What we claim as our-invention is:

l. In a water closet, the combination with a bowl, of a flushing tankintegral with said bowl and having an apertured bottom approximately atthe level of the water seal in said bowl, a channel beneath the bottomof said tank extendi to the bowl and opening therein beneat the normalwater seal,a flushing valve controlling the aperture in said bottom, andan extension of said channel rising within the tank to above the normalwater level therein and open at its upper end to constitute an overflow.

2. Ina water closet, the combination with a bowl, a flushin tankintegral therewith of a valve control ed channel connecting said tankwith said bowl at a point below the water seal of the latter, and anextension of said channel rising in said tank to a point above thenormal level constituting an overflow connection in constantcommunication with the bowl.

3. In a water closet, the combination with a bowl, a flushing tankintegral therewith, of a channel connecting said tank with said bowlhaving a port opening through the bottom of tlie tank, a valve forcompletely closing said port, and an extension of said channel rising toa point above the normal water level in the tank and integral therewithconstituting a normal open overflow connection.
